Is Mueller Industries, Inc. (MLI) the Best Stock to Buy from Mario Gabelli’s Stock Portfolio?

We recently published a list of Mario Gabelli Stock Portfolio: 10 Best Stocks to Buy. In this article, we are going to take a look at where Mueller Industries, Inc. (NYSE:MLI) stands against the other Mario Gabelli-approved stocks.

GAMCO Investors, Inc., formerly Gabelli Asset Management Company, is a prominent American firm, which has its headquarters in Rye, New York. The company specializes in offering investment advice and brokerage services to mutual funds, institutional clients, and select investors. The company was founded and is majority-owned by Mario Gabelli, who earned over $750 million in compensation over the past several years.

Veteran investor Mario Gabelli has earned millions of dollars by betting on the unloved. He likes to invest in companies that are NOT being followed or that are NOT being covered by Wall Street analysts. If the companies are not forming part of an index, it makes them even more appealing.

The hedge fund manager remains committed to active value investing. His investment philosophy of focusing on value stocks over growth stocks prevailed even when passive-index funds and Nasdaq “FAANG” dominated the market during the US Fed’s loose interest-rate policies. His investing secret is simple– “Find a good business having good management, buy the stock at a reasonable price, and then hold that stock for the long term.”

As per Insider Monkey’s 2Q 2024 database, out of the total investment portfolio, ~21.7% accounts for Industrial goods.

What Lies Ahead for the US Stock Market as Per Gabelli Funds

Gabelli Funds believes that the US Presidential election is expected to add to market volatility in 2H 2024. At the same time, the much-anticipated rate cuts in September might give a boost to rotation into areas of the market that have lagged during the year. The investment management firm sees increased volatility in the election. That being said, the economic weakness and volatility are expected to be offset by the underlying rotation and lower rates.

Gabelli seems to be optimistic about the broader US economy. He believes that companies have healthy cash flows and that gross margins are better. The only thing that might weigh over the US equities is the geopolitical risk.

Gabelli recently appeared in the prestigious Barron’s Roundtable discussion. He believes that World GDP, which is measured by the International Monetary Fund, is expected to be ~$115 trillion in 2025. The U.S. is 26%, and China is 17%. The consumer makes up for ~70% of the U.S. economy, and industrial spending accounts for ~12%.

Mario Gabelli mentioned that the US Fed is focused on the four R’s. The first is keeping “rates high for longer.” The second R is “continued runoff of the central bank’s balance sheet,” now occurring at a $60 billion pace monthly, down from ~$95 billion in early 2024. Next, the US Fed continues to make efforts to “reduce aggregate demand.” However, the higher government spending continues to offset these efforts. Finally, the Chairman continues to be “rhetoric about bringing the inflation down.”

Mergers and acquisitions (M&As) and other financial engineering strategies are expected to ramp up substantially, for numerous reasons. Gabelli believes that several private equity funds are about to see the end of their 10-year life cycles, and limited partners (LPs) need liquidity. Therefore, this situation will lead to higher sales. Mario Gabelli expects M&A to pick up globally in 2H 2024.

While the S&P 500 is up over ~15% on a YTD basis, the veteran investor believes that stocks can compound at ~8% annual growth rate in the upcoming years, significantly higher than the earnings from fixed-income securities.

Mario Gabelli is Optimistic About These Sectors

Mario Gabelli seems to gain interest in the sports franchises. This is because sports will remain central to linear television and streaming. The buzz is that media companies are shelling out hefty sums for broadcasting and streaming rights.

Moving on, the veteran hedge fund manager believes that artificial intelligence is a great technology, just like other market experts.

Gabelli’s next pick is natural gas. He believes that, over the next few years, there is a huge potential for prices to increase. This is because some producers are capping wells or producing less and demand continues to pick up as compared to power generators and liquefied natural gas exports.

Mueller Industries, Inc. (NYSE:MLI)

GAMCO Investors’ Stake Value: $189.3 million

Percentage of GAMCO Investors’ 13F Portfolio: 2.05%

Number of Hedge Fund Holders: 25

Mueller Industries, Inc. (NYSE:MLI) is engaged in making copper, brass, aluminum, and plastic products. It works through 3 business segments: piping systems, industrial metals, and climate. Over the past few years, the company has benefited from higher demand in the construction and industrial sectors.

In 2013, its gross margins were hovering somewhere around 13%. In FY 2023, its gross margins were over ~23%. Therefore, the company has strong and sustainable pricing power on its goods. Over the short to medium term, Mueller Industries, Inc. (NYSE:MLI) is expected to be supported by an expected rebound in construction activity and interest rate cuts. The company’s diversified product line, serving numerous sectors, together with its strong distribution network should continue to act as growth drivers.

Wall Street analysts opine that continued investments in infrastructure and construction might support the company as these sectors are the main drivers of demand for its products. Recently, the company indicated undertaking a $20 million investment at the U.K. tube mill and refinery. This will enable copper tube mills to melt and recycle the scrap. Moreover, the company recently highlighted that its internal investments continue to pay off. It expects these investments to yield even greater benefits as and when market conditions improve.

Its acquisition of Nehring Electrical Works, which was completed during 2Q 2024, gives a substantial platform for expansion in the energy infrastructure space. As per Insider Monkey’s 2Q 2024 database, 25 hedge funds were long Mueller Industries, Inc. (NYSE:MLI).

Diamond Hill Capital, an investment management company, released its third-quarter 2023 investor letter and mentioned Mueller Industries, Inc. (NYSE:MLI). Here is what the fund said:

“We also initiated short positions in Mueller Industries, Inc. (NYSE:MLI), Bank of Hawaii, Alarm.com Holdings and Garmin in Q3. Mueller Industries is a leading producer of copper tubes and pipes for plumbing and HVAC systems — a cyclical industry with largely commoditized products that has seen meaningful margin gains in recent years tied to tailwinds we anticipate will likely reverse in coming years. Further, we expect long-term volume trends will likely remain sluggish as copper piping continues losing share to plastic over time. Given our expectation earnings power will revert to historical levels over time, we initiated a short position during the quarter.”

Overall MLI ranks 2nd on our list of best stocks to buy according to Mario Gabelli. While we acknowledge the potential of MLI as an investment, our conviction lies in the belief that some deeply undervalued AI stocks hold greater promise for delivering higher returns, and doing so within a shorter timeframe. If you are looking for a deeply undervalued AI stock that is more promising than MLI but that trades at less than 5 times its earnings, check out our report about the cheapest AI stock.

Disclosure: None. This article is originally published at Insider Monkey.

The $250 Trillion AI Hype is Real. A few years from now, you’ll probably wish you’d bought this stock.

When Jeff Bezos said that one breakthrough technology would shape Amazon’s destiny, even Wall Street’s biggest analysts were caught off guard.

Fast forward a year and Amazon’s new CEO Andy Jassy described generative AI as a “once-in-a-lifetime” technology that is already being used across Amazon to reinvent customer experiences.

At the 8th Future Investment Initiative conference, Elon Musk predicted that by 2040 there would be at least 10 billion humanoid robots, with each priced between $20,000 and $25,000.

Do the math. According to Musk, this technology could be worth $250 trillion by 2040.

Put another way, that’s roughly equal to:

  • 175 Teslas
  • 107 Amazons
  • 140 Metas
  • 84 Googles
  • 65 Microsofts
  • And 55 Nvidias

And here’s the wild part — this $250 trillion wave isn’t tied to one company, but to an entire ecosystem of AI innovators set to reshape the global economy.

It’s a leap so massive, it could reshape how businesses, governments, and consumers operate worldwide.

Even if that $250 trillion figure sounds ambitious, major firms like PwC and McKinsey still see AI unlocking multi-trillion-dollar potential.

How could anything be worth that much?

The answer lies in a breakthrough so powerful it’s redefining how humanity works, learns, and creates.

And this breakthrough has already set off a frenzy among hedge funds and Wall Street’s top investors.

What most investors don’t realize is that one under-owned company holds the key to this $250 trillion revolution.

In fact, Verge argues this company’s supercheap AI technology should concern rivals.

Before I reveal the details, let’s talk about how some of the richest people on the planet are positioning themselves.

  • Bill Gates sees artificial intelligence as the “biggest technological advance in my lifetime,” more transformative than the internet or personal computer, capable of improving healthcare, education, and addressing climate change.
  • Larry Ellison — through Oracle, is spending billions on Nvidia chips and partnering with Cohere to embed generative AI across Oracle’s cloud and apps.
  • Warren Buffett — not known for tech hype — says this breakthrough could have a ‘hugely beneficial social impact.

When billionaires from Silicon Valley to Wall Street line up behind the same idea — you know it’s worth paying attention to.

Even as we admire what Tesla, Nvidia, Alphabet, and Microsoft have built, we believe an even greater opportunity lies elsewhere…

But the real story isn’t Nvidia — it’s a much smaller company quietly improving the critical technology that makes this entire revolution possible.

And judging by what I’m hearing from both Silicon Valley insiders and Wall Street veterans…

This prediction might not be bold at all:

A few years from now, you’ll wish you’d owned this stock.

AI, Tariffs, Nuclear Power: One Undervalued Stock Connects ALL the Dots (Before It Explodes!)

Artificial intelligence is the greatest investment opportunity of our lifetime. The time to invest in groundbreaking AI is now, and this stock is a steal!

AI is eating the world—and the machines behind it are ravenous.

Each ChatGPT query, each model update, each robotic breakthrough consumes massive amounts of energy. In fact, AI is already pushing global power grids to the brink.

Wall Street is pouring hundreds of billions into artificial intelligence—training smarter chatbots, automating industries, and building the digital future. But there’s one urgent question few are asking:

Where will all of that energy come from?

AI is the most electricity-hungry technology ever invented. Each data center powering large language models like ChatGPT consumes as much energy as a small city. And it’s about to get worse.

Even Sam Altman, the founder of OpenAI, issued a stark warning:

“The future of AI depends on an energy breakthrough.”

Elon Musk was even more blunt:

“AI will run out of electricity by next year.”

As the world chases faster, smarter machines, a hidden crisis is emerging behind the scenes. Power grids are strained. Electricity prices are rising. Utilities are scrambling to expand capacity.

And that’s where the real opportunity lies…

One little-known company—almost entirely overlooked by most AI investors—could be the ultimate backdoor play. It’s not a chipmaker. It’s not a cloud platform. But it might be the most important AI stock in the US owns critical energy infrastructure assets positioned to feed the coming AI energy spike.

As demand from AI data centers explodes, this company is gearing up to profit from the most valuable commodity in the digital age: electricity.

The “Toll Booth” Operator of the AI Energy Boom

  • It owns critical nuclear energy infrastructure assets, positioning it at the heart of America’s next-generation power strategy.
  • It’s one of the only global companies capable of executing large-scale, complex EPC (engineering, procurement, and construction) projects across oil, gas, renewable fuels, and industrial infrastructure.
  • It plays a pivotal role in U.S. LNG exportation—a sector about to explode under President Trump’s renewed “America First” energy doctrine.

Trump has made it clear: Europe and U.S. allies must buy American LNG.

And our company sits in the toll booth—collecting fees on every drop exported.

But that’s not all…

As Trump’s proposed tariffs push American manufacturers to bring their operations back home, this company will be first in line to rebuild, retrofit, and reengineer those facilities.

AI. Energy. Tariffs. Onshoring. This One Company Ties It All Together.

While the world is distracted by flashy AI tickers, a few smart investors are quietly scooping up shares of the one company powering it all from behind the scenes.

AI needs energy. Energy needs infrastructure.

And infrastructure needs a builder with experience, scale, and execution.

This company has its finger in every pie—and Wall Street is just starting to notice.

Wall Street is noticing this company also because it is quietly riding all of these tailwinds—without the sky-high valuation.

While most energy and utility firms are buried under mountains of debt and coughing up hefty interest payments just to appease bondholders…

This company is completely debt-free.

In fact, it’s sitting on a war chest of cash—equal to nearly one-third of its entire market cap.

It also owns a huge equity stake in another red-hot AI play, giving investors indirect exposure to multiple AI growth engines without paying a premium.

And here’s what the smart money has started whispering…

The Hedge Fund Secret That’s Starting to Leak Out

This stock is so off-the-radar, so absurdly undervalued, that some of the most secretive hedge fund managers in the world have begun pitching it at closed-door investment summits.

They’re sharing it quietly, away from the cameras, to rooms full of ultra-wealthy clients.

Why? Because excluding cash and investments, this company is trading at less than 7 times earnings.

And that’s for a business tied to:

  • The AI infrastructure supercycle
  • The onshoring boom driven by Trump-era tariffs
  • A surge in U.S. LNG exports
  • And a unique footprint in nuclear energy—the future of clean, reliable power

You simply won’t find another AI and energy stock this cheap… with this much upside.

This isn’t a hype stock. It’s not riding on hope.

It’s delivering real cash flows, owns critical infrastructure, and holds stakes in other major growth stories.

This is your chance to get in before the rockets take off!

Disruption is the New Name of the Game: Let’s face it, complacency breeds stagnation.

AI is the ultimate disruptor, and it’s shaking the foundations of traditional industries.

The companies that embrace AI will thrive, while the dinosaurs clinging to outdated methods will be left in the dust.

As an investor, you want to be on the side of the winners, and AI is the winning ticket.
